implemented  and  evaluated.  This  framework  could 
then  be  expanded  at  an  international  level,  and 
differences  between  regions  could  be  further 
illuminated. 
Moreover, there is the need to take a further look 
into the success factors. Each success factor could be 
presented and elaborated deeper. Therefore, e.g., the 
development of a Data Governance Structure would 
be important for city stakeholders and future research. 
Cities  and  future  research  must  further  ensure  the 
security of urban data and infrastructure. 
Additionally, examining the impact of emerging 
technologies such as artificial intelligence or further 
sustainability potentials on Urban Data Spaces could 
be an interesting avenue for future research.
